Did Harbs apologize for allowing this to happen again?
If this has happened before while he was the HC and he didn't do anything to prevent it before the game, or with his halftime speech, we can only conclude it happened with his blessing.
If he wanted this to never happen again he 100% can stop it.
Suspend every one of them that went over to taunt and especially the dickhead that went into the tunnel. He fucked around and found out, but also put egg on the face of his program.
